Description

Technical Field

[0001] This utility model specifically relates to the field of electric grafting knife technology, and more specifically to an electric grafting knife for hawthorn grafting. Background Technology

[0002] Hawthorn grafting involves selecting plump, current-year buds from healthy, disease-free hawthorn trees. A horizontal cut is made 0.5 cm above the bud, reaching the xylem. Then, a slanted cut is made 1 cm below the bud, creating a shield-shaped bud piece. The bud piece is then gently pried off. The scion should be at least 15 cm long and contain 3-4 plump buds. The lower part of the scion is then shaped into a wedge, with the length of the wedge's bevel matching the depth of the cut on the rootstock, generally 3-4 cm. Both bevels should be smooth and even.

[0003] Chinese Patent Application No. 202020576758.0 discloses an industrial pneumatic scissor, including a base, a mounting seat fixedly provided at one end of the base, a slot provided at the other end of the base, a rectangular through hole provided at one end of the slot, a cutter head assembly provided on one side of the rectangular through hole, and a pushing mechanism provided on the other side of the rectangular through hole. The cutter head assembly includes a first cutter handle, a first cutter head fixedly provided at one end of the first cutter handle, and one end of the first cutter handle being fixedly provided inside the mounting seat by bolts. A second cutter handle is movably connected to the first cutter handle through a rotating shaft, and a second cutter head is fixedly provided at one end of the second cutter handle.

[0004] In the aforementioned patent, the first and second blades form an acute angle when closed. In this case, when cutting hawthorn branches, it is difficult to apply force, especially when cutting thicker branches, because the branches are round. Furthermore, the branches tend to slide outwards, making it impossible to guarantee a one-time cut. Utility Model Content

[0005] The purpose of this utility model is to provide an electric scion cutter for hawthorn grafting, which optimizes the moving and stationary blades to form an arc-shaped blade during cutting. This prevents the branches from slipping, ensuring successful cutting of the branches in one go and greatly improving work efficiency; thus solving the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-6 In this embodiment of the utility model, an electric scion cutter for hawthorn grafting includes a fixed blade 5 and a movable blade 6 for cutting hawthorn branches; wherein the fixed blade 5 is fixed to a fixed block 4 by a countersunk bolt; the fixed blade 5 and the movable blade 6 are movably connected by a T-shaped shaft 15.

[0029] One end of the T-shaped shaft 15 has an external thread, and a gear nut 13 is installed on the outside of the external thread. A gear is welded to the inside of the nut, or a tooth profile is opened on the inside of the nut to form a gear nut 13. The T-shaped shaft 15 serves as a hinge between the fixed blade 5 and the movable blade 6. Long-term use will cause the nut on the outside of the T-shaped shaft 15 to loosen. This will increase the gap between the fixed blade 5 and the movable blade 6, resulting in uneven force during shearing, and thus making it impossible to stably cut the branches.

[0030] Therefore, a stop 14 is snapped onto one side of the gear nut 13; the stop 14 is fixed to the fixing block 4 by bolts; the stop 14 is used to lock and position the gear nut 13 to prevent the gear nut 13 from loosening, and to ensure that the installation positions of the fixed blade 5 and the movable blade 6 remain unchanged, thereby facilitating the cutting of branches.

[0031] The blade of the movable blade 6 is arc-shaped with its opening facing downwards; the blade of the fixed blade 5 is arc-shaped with its opening facing upwards.

[0032] Both the movable blade 6 and the fixed blade 5 have curved blades. With the above design, when the movable blade 6 and the fixed blade 5 are closed, the gap in the middle of the blades is larger than the gaps on both sides. Therefore, when cutting branches, the branches can be prevented from sliding, thus ensuring the cutting effect of the movable blade 6 and the fixed blade 5.

[0033] In this embodiment, a lighting component 9 is fixed to one side of the fixing block 4; the lighting component 9 includes a fixing plate 91, and a clamp 92 is fixed to the fixing plate 91; a lighting lamp 93 is snapped onto the clamp 92.

[0034] By adopting the above technical solution, the lighting lamp 93 is fixed on the clamp 92. When the light is poor, turning on the lighting lamp 93 can provide illumination, so that the staff can observe the plump buds on the branches and ensure that each cut branch is suitable for grafting.

[0035] In this embodiment, the clamp 92 has a C-shaped part for fixing the lighting lamp 93. One end of the C-shaped part is welded and fixed to the fixing plate 91, while the other end is suspended. The clamp 92 is also fastened with a buckle 94.

[0036] By adopting the above technical solution, one end of the clamp 92 is suspended, which facilitates the installation and removal of the lighting lamp 93. After the lighting lamp 93 is installed, it is fastened and locked using the buckle 94, thereby ensuring the stable clamping of the lighting lamp 93.

[0037] It should be noted that the lighting lamp 93 uses commercially available products with independent power supply, so the battery of the lighting lamp 93 can be removed and replaced or recharged.

[0038] In this embodiment, the lower end of the movable blade 6 is movably connected to the movable component 7 via a rotating shaft, and the other end of the movable component 7 is movably connected to the L-shaped connector 8 via a rotating shaft; the L-shaped connector 8 is fixed to the drive assembly 1.

[0039] More specifically, the drive assembly 1 includes a housing 10, inside which a piston rod 11 is provided, and the outer end of the piston rod 11 is fixed to an L-shaped connector 8; a pneumatic switch 12 is also provided on the outside of the housing 10; the pneumatic switch 12 is also connected to the air pipe 2.

[0040] By adopting the above technical solution, the air pipe 2 is connected to the air source. After the air source is introduced, the pneumatic switch 12 is pressed, and the gas pushes the piston rod 11 to move backward. With the cooperation of the movable part 7 and the L-shaped connector 8, the piston rod 11 pulls the movable blade 6 to close at the fixed blade 5, thereby realizing the cutting of the branches.

[0041] After the pneumatic switch 12 is released, gas is supplied in the reverse direction, the piston rod 11 moves forward, and the movable knife 6 is opened.

[0042] It should be noted that the drive component 1 is the same as the drive element of the CT-310 vertical pneumatic shear. As this is existing technology, its specific principle will not be elaborated here.

[0043] The working principle of this utility model is as follows: the air pipe 2 is connected to the air source. After the air source is introduced, the pneumatic switch 12 is pressed, and the gas pushes the piston rod 11 to move backward. With the cooperation of the movable part 7 and the L-shaped connector 8, the piston rod 11 pulls the movable blade 6 to close at the fixed blade 5. The blades of both the movable blade 6 and the fixed blade 5 are arc-shaped. With the above-mentioned design, when the movable blade 6 and the fixed blade 5 are closed, the gap in the middle of the blade is larger than the gaps on both sides. Therefore, when cutting branches, it can prevent the branches from sliding, thereby ensuring the cutting effect of the movable blade 6 and the fixed blade 5. After the pneumatic switch 12 is released, the gas is supplied in the reverse direction, and the piston rod 11 moves forward, realizing the opening of the movable blade 6.

[0044] The lighting lamp 93 is fixed to the clamp 92. When the light is poor, turning on the lighting lamp 93 can provide illumination, so that the staff can observe the plump buds on the branches and ensure that each cut branch is suitable for grafting.
